hyfmt, a codebase formatting tool in the style of ruff using beautifhy

[abidsikder]

Using Ati Sharma's beautifhy I made a simple tool called hyfmt to auto format and/or check the formatting of the Hy files in a codebase for CI!

I made this since I've picked up Hy while learning some python data science tooling and was wanting an auto formatter in the style of ruff, which I use on my other python projects.

It's in alpha stages so lots of warts...😅 but I'll hopefully address them as I dogfood this on my own codebases.
